Apple must pay for an independent antitrust monitor as part of a permanent injunction handed down on Friday by a federal court in New York. In addition, the court ruled that Apple could not strike deals with five major publishers if the terms would limit the ability to offer discounts.

Apple had settled with the five publishers before Apple's case went to trial
last July. The companies had been accused of being co-conspirators in the
case.

The injunction is set to last five years but could be extended if Apple is
found to be in noncompliance with the terms.

In July, a Judge found that Apple had colluded with the five publishers in a
scheme to raise e-book prices. Apple and the publishers had teamed up in an
attempt to break the dominant position of market leader Amazon.com, which
had established lower e-book prices that had left the publishers grumbling.
